Let me start by saying I have been using this app for around 4 years now and I love it! But ever since it came out with the whole “premium membership” thing I miss some aspects that I used to have. I no longer receive emails basically as a summary of my last cycle and I used to look forward to receiving those, it helped me get a better understanding of my cycle. And I don’t know if that is a feature in the premium membership I just noticed that when the app came out with premium membership I stopped receiving those emails, and personally I think that’s something everyone should have the privilege of receiving premium membership or not. But i also wish the app was a little more descriptive with its data, or at least had more options. For exercising I wish it had more options, it only has things like running and swimming but what about those who weight lift or walk? There are other things I wish it had as well like dizziness or how much you ate in a day or anxiety/depression, some of these things may already be on there some of them may not but I still think it’s good to have them/look into more options to collect data for. Overall, this app is great with tracking my period I just wish it went a little more in depth and helped you understand what all of it meant like it used to.
Love it, but a suggestion
I really love clue, it’s a really easy place to keep track of everything related to my cycle.
One thing I would like to suggest is to allow us to choose if we want to log our flow (or other things) multiple times a day or just once like it is now. Personally I would love to be able to mark my flow each time I use the restroom/change my tampon/pad and have clue give me the average flow for that day. I just thought this would be a nice option since I know I sometimes have trouble deciding what I want to mark a whole days flow as (like if I’m light in the morning and night but heavy in the middle of the day).
Another part of this would be to be able to log the time (if you choose), like if I get my period at 11 pm (when I normally get it in the morning). I have a really hard time remembering when I got my period and most of the time if it starts later at night it’ll go an extra day long. So it would be nice to be able to see what time I got my period, and (if marking the time for each restroom break) over time you could be able to recognize patterns of your flow throughout each day of your period.
Just a couple of thoughts, but I love this app. Thanks in advance for reading my suggestions!
Developer Response ,

I love the way this app works. It makes predictions for you (after a cycle or two it gets more accurate) and you can customize notifications to however you want them to be displayed. For me personally, it doesn’t work as well as it would for most women because my period is irregular, so the averages don’t work accurately. However, the functions on the app work perfectly and any issues I have are almost guaranteed to be caused by my own inconsistencies. I know my period isn’t ever going to become regular because of my genes, but it’s convenient to have all of my menstrual information in one place in case I need to look back at the dates during an appointment. Love this app :)
HOWEVER. Because of my irregular period, the averages show that my average cycle length is around 46 days, which is okay and all, but because that number is so high, there’s a little icon with an exclamation point on it. If I click on it, it tells me I need to buy the subscription to receive more info. It makes me really frustrated!! Clearly Clue is trying to tell me something about my menstrual health that could be helpful to my situation, but I need to pay in order to receive that insight. It doesn’t help that the icon looks really urgent and important.
